To all whom it may concern:

-- Be it known that I, Bonner S. MILLER, a

citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Car-Door Fastenings, of which the following is a specification. Y

The invention relates to car door fastenings of the type ordinarily employed with seals for indicating the unauthorized open ing of the doors. The invention has for its primary objects, the provision of an improved construction wherein the withdrawal of the bolt without breaking the sealing wire or hand is rendered imposslble, and the provision of an improvedstop construction for Fi 3 and 4 are sections on the lines IIL- II and IV-IV respectively, of Fig. 1, Fig. 4 being on an enlarged scale. Referring to the-general arrangement of parts as illustrated in Figs. land 2, 1 is the.

slide door; 2 is the post; 3 is the door stop; 4 is the staple secured to the slide door and carrying the usual hasp 5 slotted at its end as indicated at 6 (Fig. 1); 7 is a plate secured rigidljgagainst the face of the door;

stop 3 and provided with the loop 8 over-g which the has 5 fits, and with the socket 9' for receiving t e bolt; and 10 is the bolt. which fits slidably through the socket 9 and the loop 8. My invention relates princi pally to the socket and bolt construction, the general arrangement of parts being otherwise old andwell known in the art.

As indicated in Fig. 4,the opposite walls of the soc..et member 9 are perforated as indicated at 11 and 12, in order to receive the sealing band or wire.' As also indicated in Fig. 4 the bolt 10 is made in U form in cross section, with the opposing walls thereof perforated as indicated at 13 and 14, Inch perforations being in alinement with the perforations 11 and 12 when the bolt'is in its lockingposition as indicated in Fi s. l and 3. In order to prevent the wit drawal of the bolt the metal band 15 is employed', carrying the usual lead seal 16.

Specification of Letters-Patent. Patentefl App-14, 1914 Fitting up inside the bolt to the rear of "the perforations and sealing strip when the bolt 1s in looking position as indicated in Fig. '3, A

- foo" is important,-

lminates the possibility of: the: bolt 3 is the lug 17. The rovision ofthis lug 17 as it bein moved to unlockedposition, without' brea (ing the seal. It will be seen that in? order to move the bolt to unlocked position while the sealing band is inpos1tion it would be necessary to draw two-thicknesses of the band or wire to the rearon each sideof the bolt. For instance taking one side'ofi the bolt, one thickness of thebandor. wirewould have to be drawn into the space between the outer face of I the bolt and the inner ,vvallof the socket, and the other length of the "band of wire would be drawn be-r face of'the lug 17. Even with the bolt havmg a relatively loose fit in the socket this is practically impossible, even with a very fine tween the-inner face of the bolt and the sursealing wire, since the spaces between the walls of the socket and the bolt, and between the bolt and lug are not sufficient to accommodate these many thicknesses of wire, and the plurality of bends thus made in the wire or band prevent its slipping longitudinally, so that any attempt to move the bolt to the rear while the wire or band is in position willshear such wire or band, thus indicatin'g the unauthorized tampering with? the fastening. .The distinction in th1s.construction over the ordinary construction-in which a solid; bolt is used, willbe readily understood when it is consideredthat with such a construction the movement of the bolt to the rear will pull only two thick-F nesses of wire between the inner surface of the socket and theouter surface of th e bolt, and it is frequently possible, particularly where a Wire is used, to pull the bolt to the rear sufiiciently to permit the unlocking of the door, without breakingthe'wire or in-, juring the seal. It will be seen that with my invention the number of thicknesses of wire which have to be crowded between the opposing surfaces is doubled, thus practibeing of malleable metal. When; the bolt is moved outward and approaches its extreme outer position these inturned edges -18 will art.

What I claim is:

1. In combination in a door fastening, a socket member provided with a pair of opposing perforated walls and:a',-lug lying between the said Walls and spaced away therefrom, and a bolt comprisin :a pair of opposing connected perforated p ates fitting slidably between the said walls of the socket member with their edges lying between the said'wa lls and the sides of the lug, the said perforations in the bolt lying in alinement.

with those of the socket member and in advance of the lug when the bolt is in its for ward or locking position.

2. In combination in a door fastening, a socket member provided with a pair of opposing perforated walls and a lug lying between the said walls and spaced away therefrom, and a hollowtbolt U-shaped in cross section fitting slidablyin the socket between the said walls of the socket member and having its walls perforated with their edges lying between the sides of the said lug and the walls of the socket member, the said perforations in the bolt lying in alinement with those in the socket member and in advance of the said lug when the bolt is in its forward position.

3. In combination in a door fastening,

asocket member provided with a pair of op posing perforated walls and a lug lying between the said walls and spaced away therefrom, and a bolt comprising a pair of opposing connected perforated plates fitting slidably between the said walls of the socket member with their edges'lying-between the Copies of this patent may be obtained for said walls and the sides of the lug, the said perforations in the bolt lying in alinement with those of the socket member when. the bolt is in its forward position, and the forward ends of the said p'lates being bent inward to engage the said lug whenthe bolt is moved to the rear and thus prevent the Y complete withdrawal of the 'bolt from the socket member.

4. In combination in a door fastening, a socket member provided with a pair of opposing perforated walls and a lug lying between the said walls andspaced away therefrom,'and a bolt comprislng a pair of opposing connected perforated plates fitting slid,- ably between thesaid .walls of the socket member with their edges lying between the said walls and the sides of the lug, the said,

perforations in the bolt lying in alinement with those of the socket member when the bolt is in its forward position, and the forward end of one of said" plates being bentin so as to engage the said lug-when the bolt is moved to the rear, thus preventing the complete withdrawalfof :the bolt from the socket member.

5. In combination in a door fastening, a socket member providedwith a pair of opposing perforated walls and a lug lying between the said walls and spaced away therefrom,vand a hollow bolt U-sha-ped in cross section fitting slidably in the socket between the said wallsof the socket member and having its walls perforated with their edges lying between the sides of the said lug and the walls-of the socket member,

the said perforations in the bolt lying in alinement with those in the socket member and the forward end of the bolt being bentin so as to engage the said lug when the bolt is moved to the rear, thus preventing thecomplete withdrawal of the bolt from the socket member.

In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
